 FIG. 1 is a schematic flowchart of a method for simultaneously uploading a keyboard key code provided by Embodiment 1 of the present invention;

 A method for simultaneously uploading a keyboard key code is provided, including the following steps:

S101. The USB data transmission channel between the keyboard and the host is enumerated as a standard key command interface having a function of transmitting a standard key code function and a non-standard key command interface having a function of transmitting a non-standard key code; According to the USB keyboard application method in the USB specification, the USB data transmission channel between the keyboard and the host is abstracted into a standard key command interface with a transmission standard key code function and a non-standard key command interface with a non-standard key code transmission function. The USB data transmission channel refers to: a keyboard side USB driver, a keyboard USB terminal, a host USB terminal, and a data transmission channel including a USB data line between the two USB terminals.

 The enumeration process is specifically as follows: First, the keyboard side defines a keyboard USB end point for transmitting data as a keyboard USB interface, and connects the keyboard USB end point to the USB end point of the host through the USB data line, after which the host sends a request to the keyboard, Requesting to obtain the keyboard information of the connected keyboard USB interface; after receiving the request, the keyboard sends the requested keyboard information to the host, and then the host obtains the information and determines the keyboard USB driver that can be provided according to the information, and loads the corresponding USB standard keyboard USB driver; Finally, after obtaining the keyboard information including the HID report descriptor, the host thinks that the information of the connected keyboard USB interface is complete, and the keyboard is configured by the keyboard USB driver, and the keyboard can be configured successfully. Data transfer with the host. At this point, the enumeration process ends. After two similar enumeration processes, the USB data transmission channel between the keyboard and the host can be enumerated as a standard key command interface with a standard key encoding function and a non-standard key command interface with a non-standard key encoding function. .

 The keyboard information includes the HID report descriptor of the keyboard, and the HID report descriptor is a descriptor required when the device is defined as an HID device. This descriptor indicates that the device supports the version number of the USB protocol, and whether there is a proprietary descriptor. , the feature definition of the descriptor, and the organization of the data when communicating between the defined host and device. The standard key command interface of this embodiment uses a standard HID report descriptor, and the non-standard key command interface uses a non-standard HID report descriptor.

The standard HID report descriptor is a general keyboard report descriptor. The first few examples are as follows: Item Tag(Value) Raw Date Usage Page (Generic Desktop) 05 01

 Input (Data, Var, Abs, NVVrp, Lin, Pref, Li ul, Bit) 81 02 The above items describe an input field, a total of 8 bits, each bit represents a button from the left ctrl key Go to the right GUI button. These 8 bits just form a byte, which is located in the first byte of the report. Its lowest bit, bit-0, corresponds to the left ctrl key. If the returned data is 1, the left ctrl key is pressed. Otherwise, the left ctrl key is not pressed. Its highest bit, bit-7, indicates the press of the right GUI key. The middle bits need to be determined according to the HID Usage Tables specified in the HID protocol. Usually used to represent special keys, such as ctrl , shift , del , etc.

 The non-standard HID report descriptor used by the non-standard key command interface is a non-universal keyboard report descriptor, which varies according to different BIOS programs in a non-standard BIOS environment. The first few examples are as follows: Item Tag(Value) Raw Date

5102. Obtain a standard key instruction that is less than or equal to a threshold value of a standard number of keys through a keyboard, parse the standard key instruction, and extract a corresponding standard key code to be executed from a preset standard key code set, and upload the The standard key code is to be executed to the host;

 At the same time, the command that is less than or equal to the threshold number of standard buttons is a standard button command, and the standard button command interface is a standard HID keyboard interface, which can be used in all BIOS environments compatible with the USB HID keyboard. The HID report descriptor for the standard button command interface uses a generic keyboard report descriptor.

 5103. Obtain a non-standard button instruction that is greater than or equal to a threshold of a non-standard button number by using a keyboard, parse the non-standard button command, and extract a corresponding non-standard button code to be executed from the preset non-standard button code set, and pass the non-standard The key command interface uploads the non-standard key code to be executed to the host.

At the same time, the instruction that obtains the threshold of the number of non-standard buttons is a non-standard button command, and the non-standard button command interface is a non-standard HID keyboard interface, which can be used in all compatible non-standard USB HID keyboards. Used in the BIOS environment. The HID report descriptor for the non-standard key command interface uses a non-standard keyboard report descriptor. In this embodiment, the non-standard button command is an instruction that is greater than or equal to the threshold of the number of non-standard buttons, and the non-standard button command may be an instruction for the number of full keyboard buttons.

 A method for simultaneously uploading a keyboard key code, the USB device of the keyboard separately enumerating a standard key instruction for uploading a threshold value of a standard number of keys less than or equal to the standard by using a keyboard, and obtaining a number of non-standard keys greater than or equal to the same by uploading through the keyboard The non-standard key command of the threshold, when the user simultaneously inputs a plurality of key commands through the keyboard, the standard button command interface and the non-standard button command interface respectively transmit information in the USB data transmission channel between the keyboard and the host, and the two actions simultaneously In the compatible standard and non-standard BIOS environment, the full keyboard key code is uploaded at the same time, and no keyboard key conflict occurs.

 BIOS (Basic Input Output System) is a set of programs that are solidified onto the motherboard's ROM chip. It is the most important basic input and output program saved by the computer, system setting information, self-test program and system after booting. Self-starting program. Its main function is to provide the lowest level, most direct hardware setup and control for the computer.

 The BIOS programs used on the computer are divided into: AWARD BIOS, AMI BIOS, PHOENIX BIOS, and other jumper-free BIOS programs and brand-specific BIOS programs such as IBM. There are currently three major types of standard motherboard BIOS, namely AWARD, AMI and PH0ENIX. However, PHOENIX has incorporated AWARD, so in terms of desktop boards, although it is labeled AWARD-PHOENIX, it is actually AWARD's BI0S. PHOENIX BIOS is mostly used on high-end 586 original brand machines and laptops, and its screen is simple and easy to operate. Except for the three major types of motherboard BIOS programs are standard BIOS environments, other BIOS programs are non-standard BIOS environments.

As shown in FIG. 2, it is a schematic flowchart of a method for uploading a keyboard key code simultaneously according to Embodiment 2 of the present invention; this embodiment adds a preset standard key code set, a preset non-standard key code set, Set the standard button number threshold and set the non-standard button number threshold.

 A method for simultaneously uploading a keyboard key code is provided, including the following steps:

 S201. Create and store a preset standard button code set corresponding to the standard button command and the standard button code information; establish and store a preset non-standard button code set corresponding to the non-standard button command and the non-standard button code information.

 The standard key code information is a plurality of key commands less than or equal to the threshold number of the standard key, including the coded information of each key and a combined sequence of a plurality of keys; the non-standard key coded information is a number of thresholds equal to or greater than the number of non-standard keys The key command includes the coding information of each key and a combined sequence of several keys.

 The keyboard is divided into an encoded keyboard and a non-encoded keyboard. The coded keyboard relies mainly on a dedicated large-scale integrated circuit to perform scanning, encoding, and transmission functions. A complete keyboard control circuit consists of a key matrix, a clock generator and a main IC. The key matrix is fabricated on the circuit board. The clock generator is used to generate a series of regular pulses. It determines the frequency of the main IC scan key matrix. All the working steps of the keyboard control circuit must be based on the rhythm sent by the clock generator. get on. The main IC sends a scan signal to the row or column of the key matrix row by row or column according to the uninterrupted pulse frequency sent by the clock generator; when a key is pressed, the corresponding scan signal is A cross-connected signal is detected by the detecting circuit in the row or column direction, and the cross-connect signal determines the coordinate position of the key; the cross-connect signal is sent to the main ic, and the encoded information of the key is generated after passing through the internal encoding circuit. , such as the ASCI I code.

The non-encoded keyboard does not directly provide the coding information of the button, but uses relatively simple hardware and a set of special programs to identify the position of the button. Non-encoded keyboards use software-driven hardware to perform functions such as scanning, encoding, and transfer. This program is called a keyboard handler. The entire keyboard processing program consists of three parts: the query program, the transfer program, and the decoding program. The main program first calls the query program, scans the key matrix matrix line by line through the query interface, and simultaneously detects the output of the row and column, which is determined by the intersection signal of the row and the column. The coordinates of a closed key, that is, the scan code corresponding to the button; the main program calls the transfer program to transfer the obtained scan code to the keyboard interface circuit located in the host; the main program calls the decoding program to translate the scan code in the keyboard interface into The encoding information of the corresponding key.

 5202. Set a standard button number threshold and a non-standard button number threshold.

 Preferably, the threshold number of the standard buttons is 6, and the threshold of the number of non-standard buttons is 7. Certainly, the threshold number of the standard button may also be 12 or 24, and the corresponding threshold number of the non-standard buttons is 13 or 25 ο.

 5203. The USB data transmission channel between the keyboard and the host is enumerated as a standard key command interface having a transmission standard key code function and a non-standard key command interface having a non-standard key code transmission function;

 A typical USB device requires a "driver" that provides a data transfer path from the application software to the USB device, but the driver programming technique is complex and can cause the system to crash if an error occurs. To this end, the operating system provides built-in drivers for some typical USB devices such as HID devices (Human Interface Device, which refers to devices that interact directly with people, such as mice, keyboards, etc.), USB HID devices. After connecting to the host, a series of data is sent to the host. This series of data indicates the type of device and the way data can be supported. These data are descriptors. A descriptor is a data result or a formatted block of information that makes the host aware of the device. Each descriptor contains information about the device as a whole or an element. All USB peripherals must respond to requests for standard USB HID report descriptors. The host uses control transfers during the enumeration to request HID report descriptors from the device.

5204. Obtain a standard button instruction that is less than or equal to a threshold number of standard buttons by using a keyboard, parse the standard button instruction, and extract a corresponding standard key code to be executed from the preset standard button code set, and upload the standard button interface. The standard key code is to be executed to the host; S205. Obtain a non-standard key command that is greater than or equal to a threshold value of a non-standard button number by using a keyboard, parse the non-standard key command, and extract a corresponding non-standard key code to be executed from the preset non-standard key code set, and pass the non-standard The key command interface uploads the non-standard key code to be executed to the host.
